Zigawo zazikulu mu mlengalenga ndi nayitrogeni ndi mpweya, ntchito yozungulira kutentha, nayitrogeni ndi mpweya mu mpweya zeolite molecular sieve (ZMS) adsorption ntchito ndi osiyana (oxygen akhoza kudutsa ndi nayitrogeni adsorption), kupanga njira yoyenera, ndi kupanga nayitrogeni. ndi kupatukana kwa oxygen kuti mupeze mpweya.
